中文摘要: 采用硫酸化微波焙烧—水浸工艺从石煤中提取五氧化二钒，考察了硫酸用量、微波功率、粒径、微波焙烧温度和时间、添加剂NaF加入量、水浸液固比、水浸温度和时间对钒、铁、铝浸出的影响。结果表明，在下述最佳工艺条件下，五氧化二钒的浸出率达90%以上：硫酸用量30%、微波功率700 W、粒径0.08 mm、200 ℃微波焙烧1 h、NaF加入量3%、水浸时间1 h、水浸液固比3︰1、水浸温度90 ℃。
Abstract:Vanadium pentoxide was extracted from stone coal by sulfation microwave roasting and water leaching. The effects of sulfuric acid dosage, microwave power, particle size, microwave roasting temperature and time, dosage of additive NaF, water leaching time, ratio of liquid to solid, and water leaching temperature on leaching rate of vanadium, iron, and aluminum were investigated. The results show that vanadium pentoxide leaching rate is 90% above under the optimum conditions including sulfuric acid dosage of 30%, microwave power of 700 W, particle size of 0.08 mm, microwave roasting temperature of 200 ℃, microwave roasting time of 1 h, dosage of NaF of 3%, ratio of liquid to solid of 3︰1, and water leaching temperature and time of 90 ℃ and 1 h respectively.
